HOSE-BILLING PRESS.

Specification of Letters Patent.

Patented Feb. 9,1915.

Application filed February 18, 1914. Serial No. 819,600.

To all whom, it may cof/wcm.'

Be it known that l, JAMES LAMB, a citizen of the United States, residingat Youngstown, in the county of Mahoning and State of Ohio, haveinvented new and useful Improvements in Hose Billing Presses, of whichthe following is a specification.

The invention relates to a hose billing press.

The primary object of the invention is the provision of a press whereinthe ends of the hose for use in train pipe couplings will be enlarged atits ends so as to receive the metal parts of a coupling so as to avoidthe possibility of the splitting of the ends of the hose when theseparts are attached thereto.

Another object of the invention is the provision of a press of thischaracter wherein the air hose is firmly held tol enlarge the endsthereof under the action of uid pressure without the possibility ofbursting the hose or splitting the same during such operation.

A further object of the invention is the provision of a press of thischaracter which is simple in construction, thoroughly reliable andefficient for the expanding of the air or steam hose at the endsthereof, and also which is inexpensive in manufacture.

With these and other objects in view, the invention consists in theconstruction, combination and arrangement of parts asvwill behereinafter fully described, illustrated in the accompanying drawing,and pointed out in the claims hereunto appended.

In the drawing Figure l is a top plan view of a press constructed inaccordance with the invention. Fig. 2 is a vertical longitudinalsectional view thereof. Fig. 3 is a sectional view on the line 33 ofFig. 1.

Similar reference characters indicate corresponding parts throughout theseveral views in the drawing.

Referring to the drawing in detail, the press comprises a hose clampingstand A formed with a tubular portion 10 in which is held the air orsteam hose 11 which is made from rubber' and vulcanized in the ordinarySpaced from opposite ends of the hose stand A are fluid cylinders 14; ineach of which is arranged a reciprocating piston 15 having its rod 16working through a stuffing box 17 in one end of the cylinder, andcarrying a conical shaped expander head or bill 18, the same beingdetachably connected thereto in any suitable manner. This head or bill18 is adapted to be passed within the end adjacent thereto of the hose11 for expanding the same. Arranged on each cylinder 11 is a valvecasing 19 fitted with a turn valve 20, and from this casing lead pipes21 which communicate with the cylinder 14 near opposite ends thereof sothat fluid may be admitted and exhausted from opposite sides of thepiston 15 for reciprocatingly moving the same within the cylinder, itbeing understood of course that the valve casing 19 is connected with afluid supply pipe 22 and an exhaust pipe 23 respectively. The valve 2Owhen actuated regulates the course of the supply fluid and the exhaustthereof to and from thecylinder so that the piston 15 will be actuatedfor moving the head or bill 18 into theend of theV hose l1 and also forremoving it therefrom. Y

The piston rod L16 is formed with a fluid passage 21- which communicateswith the cylinder 111 and also opens intothe fluid space 25 formed inthe head or bill 18 so that steam from the cylinder 11 will flow intothe space 25 for heating the head or bill 18, whereby it will bemaintained heated for action on the hose to enlarge the ends thereofwithout possibility of the splitting or breaking of the hose during theopera tion of the press.

From the foregoing it is thought that the construction and manner ofoperation of the device will be clearly understood, and therefore a moreextended explanation has been omitted.

What is claimed is 1. A press of the class described comprising a pairof spaced fluid cylinders, a reciprocating piston working within eachcylinder and having a stem provided with a fluid vent opening throughits outer end and communicating with the cylinders, a conicalshapedhollow member supported on the outer end of the stem and adapted toreceive fluid from the cylinder, and means for holding a section of hosebetween the cylinders and in alinement with the member.

2. A press of the class described comprising a pair of spaced fluidcylinders, a reciprocating piston working within each cylinder andhaving a stem provided with a fluid vent opening through its outer endand communicating with the cylinders, a conicalshaped hollow memberdetachably supported on the outer end of the stem and adapted to receivevfluid from the cylinder, and means for holding a section of hosebetween the cylinders and in alinement with the member.

3. A press of the class described comprising a pair of spaced fluidcylinders, a reciprocating piston working within each cylinder andhaving a stem provided with a fluid vent opening through its outer endand communicating with the cylinders, a conicalshaped hollow memberdetachably supported on the outer end of the stem and adapted to receivefluid from the cylinder, means for holding a section of hose between thecylinders and in alinement with the member, and means for admitting andexhausting fluid to and from the cylinders.

4. A press of the class described comprising a pair of spaced fluidcylinders, a reciprocating piston working within each cylinder andhaving a stem provided with a fluid vent opening through its outer endand communicating with the cylinders, a conical-shaped hollow memberdetachably supported'on the outer end of the stern and adapted toreceive fluid Jfrom the cylinders, means for holding a section of hosebetween the cylinders and in alinement with the member, means foradmitting and eX- hausting fluid -to and from the cylinders, and flaredends formed on the hose holder to embrace the hose when the members areinserted therein.

5. A press of the class described comprising a pair of spaced fluidcylinders, a reciprocating piston working within each cylinder andhaving a stem provided with a fluid vent opening through its outer endand communicating with the cylinders, a conical-shaped hollow memberdetachably supported on the outer end of the stem and adapted to receivefluid from the cylinders, means for'holding a section of hose betweenthe cylinders and in alinement with the member, means for admitting andexhausting fluid to and from the cylinders, and flared ends formed onthe hose holder to embrace the hose when the members are insertedtherein, and means for supporting the cylinders and holders.

6. A press of the class described comprising a pair of spaced fluidcylinders, a reciprocating piston working within each cylinder andhaving a stem provided with a fluid vent opening through its outer endand communicating with the cylinders, a conical-shaped hollow memberdetachably supported on the outer end of the stem and adapted to receiveHuid from the cylinders, means for holding a section of hose between thecylinders and in alinement with the member, means for admitting andexhausting fluid to and from the cylinders, flared ends formed on thehose holder to embrace the hose when the members are inserted therein,means for supporting the cylinders and holders, and a swinging clampingsection on the holder.

In testimony whereof I afiix my signature in presence of two witnesses.
